AI Technical Summary

Benefits of technology

The present invention provides a dishwasher with a filtering unit that can effectively filter washing water. Additionally, the invention prevents the filtering unit from deforming or becoming blocked with dirt, even when water pressure is applied.

Problems solved by technology

However, the aforementioned dishwasher has several problems.

Since the dishwasher repeats drainage and resupply of the washing water, even though the clean washing water is periodically supplied to the dishwasher, if the filter is stopped up with dirt before the water is resupplied, a problem occurs in that it is impossible to filter the washing water.

Also, if the filter is stopped up with dirt, since the circulating pump circulates the washing water at the higher water pressure, a problem occurs in that deformation of the filter may be caused.
